Subject Re: Giraph Metrics showing communication time zero for SimpleShortestPathsComputation example
Date Mon, 13 Jul 2015 10:34:58 GMT
Hi Arjun,

I could not figure out the solution. But in case of page-rank example I
Observed non zero values for the same field.

It would be really great if some one can explain what does superstep
time,compute all partitions, network communication time  in the metric
information exactly mean?

Is compute all partitions + network communication time + synchronization
overhead =superstep time or *is network communication time is included in
the compute time itself*?

Thanks
Ravikant
